Title: Improved reversing gear for internal combustion engines
IPC: F01L13/00
Filed: 1927-09-02
Abstract: 301,543. Petersen, O, Sept. 2, 1927. Cam-actuated and lever-actuated pumps; buffers, springs, and the like; regulating delivery by bye-passes or return circuits.-In an internal-combustion engine, having a solid-injection fuel pump actuated by cams upon an axially movable shaft, reversing being controlled through a manoeuvring shaft, an interlocking connection is provided so that the pump cannot deliver fuel when the starting lever is in the "stop" position. In one form, Figs. 1 and 3, the levers 5, 6, 7 for ,the engine valves and the fuelpump lever 16 are pivoted about eccentrics 2, 3, 4, 15 on the manoeuvring shaft 1 and are actuated by cams 8-10 and 18<a> on a shaft 14. For reversing, the shaft 1 is turned to lift the levers from their cams, and the shaft 14 is moved axially to bring cams 11-13 and 18b into position. The movement of the shaft 1 for reversal is effected through worm gearing 26 by a motor 27 controlled by a lever 29, and the axial movement of the cam shaft 14 is effected by a cam 25 on the shaft 1 engaging between collars 25a, 25b on the shaft 14. A lever 35 connected to the pump plunger 21 carries a plunger for lifting an overflow valve 33 during reversal, and is pivoted upon an eccentric 36 connected by a link 38 to a lever 32 for starting the engine by compressed air. In a modification, Fig. 4, the cam-actuated lever 16, pivoted on an eccentric 15 on the manoeuvring shaft 1, is connected at one end by tension rods 52 to a cross-head 51 on the pump plunger 21. The other end 41 of the lever is provided with a hole 42 for the passage of a rod 43, pivoted at 44, and passing through a disc 47 connected by tension-rods 49 to pivots on the head 41, a spring 46 being interposed between the disc 47 and a disc 45 on the rod 43. In another modification, the manoeuvring shaft carries a cam for moving the fuel-pump lever out of contact with its cam while reversing is effected. An overflow opening in the pump is opened during reversal by a rotary valve connected to the starting lever, or by a slide valve, actuated by a lever connected at one end to a pivot on the pump plunger and at the other end to the starting lever. In a further modification, the pump cams are mounted on a separate shaft geared to the shaft 14, axial movement of the two shafts for reversing being effected simultaneously by a fork engaging collars on the shafts. In a multicylinder engine, a single overflow or other valve may be provided for relieving the fuel pressure during reversing, the casing of this valve being connected by piping to spring- loaded check valves on the pumps.

Title: Push-start circuit
IPC: F02N15/10
Filed: 1966-05-24
Abstract: 1,101,319. Variable-ratio gears. CLARK EQUIPMENT CO. 24 May, 1966 [7 June, 1965], No. 23187/66. Heading F2D. [Also in Division F1] A push-start circuit for a vehicle with a power-shift transmission 20 and a torque converter 18, comprises an output driven pump 164 and a control valve 214 which is biased by a spring 176 to the position shown in which the pump 164 discharge, which is supplied to a port 206, is connected through a port 208 with a line 234 to supply liquid to the servo system for push-starting. An input driven pump 40 supplies liquid to a port 210 of the valve 214 which, in the position shown connects the port 210 to an inlet port 192 of the output driven pump 164. A passage 222 in the spool of valve 214 admits the discharge pressure of pump 40 to the right-hand end of the spool, so that when the input speed is sufficiently high the spool is shifted to the left to communicate the main pump 40 discharge with the servo supply port 208 and to interconnect the output pump 164 discharge and intake ports 206, 192. The output pump 164 draws from a reservoir 46 by way of a port 194, check valve 196 and port 192. When the input pump 40 is operative to supply the servo pressure, restricted passages 212, 204 ensure an interchange of liquid from the pump 40 to the output pump 164 circuit and to the reservoir to cool the liquid in the output pump circuit. The transmission and control system is described in Specification 1,083,429.

Filed: 1949-09-08
Abstract: 676,442. Winding yarn. SCRAGG, Ltd., S. & E., and SCRAGG, S. Dec. 1, 1950 [Sept. 8, 1949], No. 23235/49. Class 120(ii) In a drum winding machine of the kind in which the thread guide is carried by a bar reciprocated longitudinally to lay the thread by a helical cam secured to a shaft C the shaft C is driven by a roller O which engages between the arms of a fork P secured to the shaft, the roller O being eccentrically mounted on an axle K which is gradually rotated about its axis and carried by a driving wheel E mounted on a sleeve D coaxially with the shaft C. The wheel E drives a compound gear G, H, on a lay-shaft J, the gear H driving a wheel F, loose on the sleeve D, to which is fixed a gear M meshing with a gear L driving the shaft K. Since the wheels F, E differ by, say, one tooth, the shaft K is gradually rotated so that the eccentrically-mounted roller O will gradually increase or decrease the rate of rotation of the shaft C and so break up ribbon winding.

Title: Fluid flow control valve and flushing system therefor
IPC: F16K5/20
Filed: 1971-04-19
Abstract: 1315297 Valves WALWORTH CO 19 April 1971 [4 May 1970] 23315/71 Heading F2V The seat members 38 of a plug valve 10 are each so dimensioned at their inner and outer faces that these members are fluid-urged towards the plug 28 regardless of whether it is the pressure P of the flow line 31 that is higher than the pressure in an annular chamber 50, or vice versa. In the former case, a rear sealing ring 46 is forced towards the plug whilst in the latter case it is forced to the position shown wherein the higher pressure in chamber 50 is sealed from the flow line 31 and acts on the seat members in a direction tending to force them towards the plug. Cleansing by flushing of the space around the trunnion 24, 26 and of an equalization passage 53 is effected by supplying cleansing liquid from a source W through line 55 to the chamber 50 and withdrawing it through line 54 which is placed in communication via line 60 with a port 62 at the upstream side of the valve. A reversing line 64 connects the supply and return lines 55 and 54, 60, respectively. Alternatively (Fig. 2, not shown), line 54 may be fed from source W and line 55 connected via line 64 to the discharge line 60. In either case the pressure of source W is preferably higher than the pressure of the flow in line 31. Furthermore, in the case where the flow through line 31 is a slurry, it is preferable to have the cleansing liquid the same as the slurry carrier, e.g. water.

Title: Improvements relating to producing a matt surface on self supporting film of thermoplastic material
Inventor: ASHWORTH NORMAN IVES
IPC: B29D7/00
Filed: 1958-07-23
Abstract: A matt surface is produced on a self-supporting film of an organic thermoplastic material by immersing the film in a suspension of abrasive particles in a liquid contained in a tank and subjecting the suspension to ultrasonic vibrations to cause the particles to impinge on one or both surfaces of the film and make minute cuts and pits on the surfaces.  The film may be continuously fed through the tank and the suspension may be vibrated by means of a plate which is immersed in the tank and subjected to ultrasonic vibrations.  The process improves the ink receptivity of the film surfaces.

Title: Hydraulic percussion tool with impact blow and frequency control
IPC: E21B1/30
Filed: 1976-06-08
Abstract: 1515442 Hydraulic reciprocating motors GARDNER-DENVER CO 8 June 1976 [5 Dec 1975] 23705/76 Heading F1A [Also in Division B4] A percussive tool comprises a casing defining a bore 18, a piston 20 disposed for reciprocating movement in the bore and including a first portion 88 dividing the bore into a first cavity 90, Fig. 5, and a second cavity 92, means 62 for introducing pressurized fluid into first cavity 90 for continuously urging piston 20 to the left, inlet port 76 and outlet port 84 for respectively conducting pressurized fluid to and from second cavity 92, a valve 102 disposed in second cavity 92 and operable to be actuated by piston 20 to open and close inlet and outlet ports 76, 84 to effect reciprocation of piston 20 and means 132, Fig. 5 or 166, Fig. 7, for setting the stroke length of piston 20 by setting the position of the piston, relative to the bore, at which valve 102 opens inlet 76 and closes outlet 84 so as to start a new power stroke. Preferably the tool is a rock drill driven by a constant power hydraulic pump. Piston 20 strikes surface 40 of shank 34. The shank is disposed in a chuck 43 which is rotatably driven by gears 44, 46, drive-shaft 48 and rotary fluid motor 50. A bit and a drill rod may be screwed on to threaded end portion 54 of shank 34. Valve 102 is a tubular sleeve having lateral openings 104 for uncovering outlet port 84 and lateral openings 106 for uncovering inlet ports 76. During the driving stroke valve sleeve 102 travels with piston 20, being engaged by split ring 110. Whilst the piston is stopped by impact with shank surface 40 sleeve 102 is stopped by the action on its endface 120 of fluid in chamber 122, Fig. 5, formed between the bore and the piston. If the fluid cannot escape from chamber 122 the sleeve is stopped instantly and maintains its position relative to piston 20. If however spool valve 132 is positioned to allow fluid to pass from chamber 122 via passage 140, recess 138, groove 136, cylinder 128 and passage 142 to cavity 92 valve sleeve 102 is halted further to the right, with respect to piston 20, at the end of the working stroke. The pressure of fluid acting on piston surface 134 against spring 144 determines the extent to which valve 132 is opened and sleeve 102 displaced and hence the length of the piston stroke. (The pressure of fluid in cavity 90 returns piston 20 and sleeve 102 to the left until the sleeve closes outlet port 84 and opens inlet 76). In the alternative embodiment of Fig. 7, chamber 122 may be vented via passages 168, 170, 172. Piston 166 is biased to uncover the passages by spring 178 and to close one or more of them pressure fluid is supplied by conduit 150.

Title: Improvements in thermostatic switches for electric heating elements
IPC: H05B1/02
Filed: 1925-09-23
Abstract: 251,510. Klettner, M. Sept. 23, 1925. Thermal switches; switches, g u i c k - action. - Switches for electric heaters comprise a diaphragm 13 actuated by the expansion or contraction of liquid in a drum 12a to cause a contact 22 to move from a contact 31 to a contact 26 or vice-versa thereby energizing one or other of two electromagnets 27, 29 arranged at right angles to each other and causing an armature 30 and a switch drum 7 to rotate through 90‹ to open or close the circuit to the heating element. The drum 7 carries contacts 8, 6, 28 all connected to each other, and brushes bear against the drum as shown. The drum also carries a member 10 adapted to complete the heat circuit from the heating element through the socket 4 to the liquid drum 12<a>. With the parts in the position shown the heating circuit is completed through the contacts 6, 8. The liquid in the drum 12a expands and a pin 14 on the diaphragm 13 pressing against a system of multiplying levers eventually causes a lever 18 having a forked end to move the contact 22 from contact 31 to contact 26, a buckled spring 20 giving a snap action. A circuit is then completed from the terminal 1 to frame 3a, conductors 25<a>, contacts 22, 26 and thence to magnet 27, contacts 28, 8 and terminal 2. The armature 30 is attracted, the drum 7 rotated through 90‹ and the electric circuit to the heater as well as the heat circuit through the member 10 interrupted. When the liquid cools, the contact 22 flies across to contact 31 thereby energizing magnet 29 through the brushes bearing on the right-hand side of the drum 7 and the drum 7 and member 10 are returned to their original position.
